Hej hej!
Najpierw zamiana jednostek :)
[tex]1 \ km=1000 \ m\\\\1 \ m=0,001 \ km[/tex]
Teraz obliczenia ↓
[tex]5 \ m=5\cdot0,001 \ km=\boxed{0,005 \ km}\\\\50 \ m=50\cdot0,001 \ km=\boxed{0,05 \ km}\\\\550 \ m=550\cdot0,001 \ km=\boxed{0,55 \ km}\\\\5500 \ m=5500\cdot0,001 \ km=\boxed{5,5 \ km}[/tex]
